MILK AND CREAM SEPARATOR.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application liled April 16, 1906. Serial No, 311.924.

To all whom t may concern.-

Be it known that I, Fairborn H. REID, a citizen of the United States,and a resident of Sioux City, in thc county of Woodbury and State ofiowa, have invented a new and irnproved Milk and Cream Separator, ofwhich the following is a specification.

My invention is an improvement in centrifugal separators in which asQ-called liner," comprising a series of metal shells of approximatelyconical form, are arranged within a drum or inverted bo'wl and the wholemounted n on a rotatable shaft, the full-milk from whie the cream is tobe separated being admitted at the center of the cones and distributedradially between them, the separation of the cream being effected bycentrifugal action and the two liquids being drawn ofi from 'the drum orbowl at separate orifices or s outs.

T e novel features of the invention are hereinafter described, andspecifically indicated in the claims.

In the accompanying draw-ings, Figure 1 is a central lo tudinal sectionof my improved separator. ig. 2 is a cross-section on the line 2 2 ofFig. 1. Fig. 3 is a cross-section on theline33oFig. 1. Fiisa lanvew ofone of the cones or coneorms. ig. 5 is a side view of the same. Fig. 6is a top view, part being broken away, of my improved milk-distributor.Fig. 7 is in part a side view and in part a vertical section of thedistributar.

The se arator proper is mounted upon a V ,irertical s aft l, which inracticc is stepped and 'ournaled in a suitab e framel and provid with aband pulley or gear to adapt it to be driven at the requisito speed by amotor of any preferred kind. The base 2 of the separator has anapproximately concave-convex form and is supported upon a shaft-collar3. The drum or bowl 4,' which is ap proximatcly conical in form, isseated upon the rim 2* of the base 2 and in a groove provided withelastic packing. A nut 4 is screwed upon the up er end of the shaft 1and bears upon the adliacent end of the drum 4 whereby the latter ispressed firmly upon the base 2 and the latter in turn upon the collar 3.Within this drum or bowl 4 :1ro contained the parts by which separationof the cream from the milk is efl'ected. The up er end of the shaft 1 ishollow, and the [ullmilk-that is to say, the milk containing is receivedinto the clon ated chamber 5 thus provided, and from t e latter it isdistributed through lateral holes G. (Sec Figs. l and 2.)

My improved distributor A (see Figs. 1 2, 6, 7) surrounds the portion ofthe shaft m1- mediatcly above the base 2 and rests upon the latter, towhich it is keyed at 7 (scc F ig. 1)that is to say, a key is inserted inregistering slots or notches provided in the adjacent ortions of thebase 2 and distributor A. The istribu ter has a hollow cylindrical bodand a series of lateral ribs S, which are cac 1 provided with a verticalrow of holes 9. The vertical projections or ribs are referably four innumber, so that milk is dischar ed from thc distributor A at four oints.he chamber formed within thc bo y of the distributor A has a reaterdiameter than the portion of the sha 't to which it is applied, as willbe apparent from an inspection of Figs. I and 7. In other words, the endopenings in the body of the distributor have the same diameter as theshaft, and thus lit it closely while an annular chamber 10 (see Five. 1and 2) is formed around the shaft. Igiito this chamber the milkdischarges from the hole 6 in the shaft, and the chamber thus serves asa rimary collector from which the flow or distrlbution of milk to theseveral rows of openings 9 occurs. Surrounding the distributar is aseries of approximately concaveconvcx plates 11, the same constitutingthe liner, which is a well-known element in separators of thischaracter.

As shown iu F ig. 5, the upper ends of the separator-plates are formedat an obtuse angle to the body or main portion thereof, whereby thcmingled milk and cream discharged l'rom the distributer A are suddenldiverted from thc lateral course downwar Blocks 1l* :irc applied to thebody or main portieri of theplatcs l1, as shown in Figs. 4, 5, and thesescrvc to separate them'from each other, as will bc understood byreference to Fig. l.

As shown in Figs. 1 and 2, one of the lat oral ribs 8 of the distributorA is rovided with a vertical flange 12 which projects laterall y beyondthe said rib, and is thus adapted to serve as a key for preventing theseveral separator-plates 1l from rotating on the distributor. Thus, asshown in F ig. 4, each of the separator-plates has a notch in its upperend, ns shown at 13, Fil7 4, adapted to rethe cream which is to beseparated from itl ceivc the key or flange and it will be un- IlOderstood that when the distributer A has been applied to the shaft and'keyed to ,the base 2, as before described, the several separator-platesare passed downward successivel over the upper end of the shaft and the`tributer, the slots 13 in said separatorlates bein brought intocoincidence or register with t ie key or flange 12 of the distributer,the separator-plates thus sliding down into place, ,as will be readilyunderstood.

Above the several separator-plates 1 1, constituting the liner, isarranged a similar seplarator-plate 14, (see Fig. 1,) the same servingin function as a cream-collector. The up )er end of such cream-collectoris constructed as a hood or cylinder 14", surrounding the shaft l andforming an annular chamber into which the cream passes and from which itescapes through a small tube 15, arranged in the head of `the casing ordrum 4. This tube 15 further serves as a means for readily connectingthe cream-collector 14 with the casit@ 4. Thus all the parts supportedupon and attached to the shaft, as has been described, are detac'hab'lyconnected therewith, 'but fixed in position so as to revolve with it. Byremoving the nut 4 the casing and streamcollector 14, attached thereto,may be readily removed and then the separator-plates 11 and thedistributer A.

As has been already substantially indicated, the full-milk is deliveredinto the chamber 5 of the shaft 1 and passes thence through the holes 6into the annular distributingchamber 10, formed between the shaft andthe apertured portion of the distributer A. 'Illience it dischargeslaterally through all the holes 9, rovided 1n the several vertical ribsS of the istributer, and is thus led directly into the spaces betweenthe separator-plates 11. The further or more complete separation of thecream from thc milk is etl'ected as they pass downward in thc spacesbetween the separator-plates and discharge therefrom against thesurrounding casing or drinn 4. The difference of specilic gravity ofthetwo li uids-cream and milk-insures that the milk, being the heavier,will accumulate and form a layer in contact with the inner side of thedrum 4, and the cream will form another layer inside the milk 4layer andin Contact therewith. The gravity of the milk [lowing from chamber 5will cause these separated liquids-cream and milk-to flow upward ,themilk, owing to its greater specific gravity, flowing along the wall ofthe drum 4 and escaping at the lateral orifices 16 formed in the headthereof, while the cream, passing into the collector 14 and between thesame and the adjacent to plate into the hood 14", discharges throng thetube 15. '[he courses of the separated li nids-cream and milk- ,are resectively in icated in Fig. 1 by singleheade and double-headed arrows.

What I claim is- 1. The improved milk and cream separator comprising avertical shaft provided with a collar, and in itsu per portion with achamber 5 having later `openings at the base, a convex base 2 seatedupon the collar and having a flanged rim, a dlstributer surrounding theapertured portion of the shaft but separated therefrom to form anannular collecting-chamber and provided with a vertical flange 12,separator-plates 11 arranged one over the other and the top plate 14having au upper extended portion constituting a cream-collecting hoodwith discharge-outlet 15, a casin or drum 4 seated upon the base .2 andhaving a milk-discharge outlet at the top, and a nut screwed upon theupper portion of the shaft whereby all the arts constituting the searator roper are he d detachably on the s aft, su stantially asdescribed.

2. The improved milk and cream separator comprising a verticai shafthaving a collar 3, a convex base 2 supported upon the collar, a casing 4seated upon the Harige or rim of the base and provided at the top withan aperture for receiving the head of the shaft and also wit-h ala-teral milk-discharge o ening, means for holding the casing in place,and the separating means proper inclosed by the casing, the sameconsisting of the distributer A surrounding the shaft and having lateraldischarge-openings, concave-convex se arator-plates extending downwardfrom t e distributer, the top plate 14 having an extended vertical andchambered portion for receiving the cream and atop discharge-passage 15,substantially as described.

3. In a separator of the class indicated, the combination, with avertical shaft having a chamber 5 with lateral discharge-openings, of adistributer surrounding the chambered portion of the shaftseparator-plates arranged thereon and the top separatorlate providedwith the upwardly-extended c amered portion constltuting acream-collector, and the convex base, and hollow casin 4 supportedthereon and inclosing the ot er specified parts of the separator proper,substantially as described.
